This invention relates to a method for inducing or enhancing the differentiation of pluripotent stem cells into cardiomyocyte via casein kinase 1 inhibition said method comprising culturing the stem cells in the presence of a medium comprising a casein kinase 1 inhibitor of the formula (I) or (II) or a stereoisomer, tautomer, or a salt thereof wherein R1, R2 and R3 independently from another represent hydrogen, optionally substituted alkyl, alkenyl, alkynyl, heterocyclyl, heteroaryl or aryl; X represents NR4, O or S; and R4 represents hydrogen, optionally substituted alkyl, alkenyl, alkynyl, heterocyclyl, heteroaryl or aryl. The method can be used in the late phase of stem cell differentiation and in the compounds of formula (I) or (II) in combination with other small molecules can lead to especially high differentiation of stem cells into cardiomyocytes. The invention further relates to novel compounds which can be used in the method of the invention and kits for stem cell differentiation.
本发明涉及一种通过酪蛋白激酶1抑制诱导或增强多能干细胞向心肌细胞分化的方法,所述方法包括将干细胞培养在含有式(I)或(II)的酪蛋白激酶1抑制剂的培养基中,或其立体异构体、互变异构体或盐中,其中R1、R2和R3独立地表示氢、可选择地取代的烷基、烯烃基、炔烃基、杂环基、杂芳基或芳基;X表示NR4、O或S;R4表示氢、可选择地取代的烷基、烯烃基、炔烃基、杂环基、杂芳基或芳基。该方法可用于干细胞分化的后期阶段,结合式(I)或(II)的化合物与其他小分子一起可导致干细胞特别高效地分化为心肌细胞。该发明还涉及可用于该方法的新化合物以及用于干细胞分化的试剂盒。
